Types of Cells


A human body is made up of trillions of cells which are tiny structures in different shapes and sizes. They are also the basic unit of living organisms, which then comprise tissues which comprise organs, which help in building the different organ systems to run the body. Each type of cell in the human body has a different role to play. Here we have listed the most common cell types in every human body which are necessary to keep it functioning.

Stem Cells

Stem cells originate from unspecialized cells which are capable of developing into specialized cells for building organs and tissues. Stem cells can also replenish and repair the tissues. The scientists use this property of replicating for building tissue for damaged organs and transplants.

Bone Cells

Bones cells are of three primary types – osteoclasts, osteoblasts, and osteocytes. These cells make the connective tissue that builds the skeletal system. Osteocytes help in the formation of bone and maintain the calcium balance in the bones. Osteoblasts produce osteoid which builds the bone matrix and forms bones. Osteoclasts are the large cells which rebuild the minerals to heal the bones.

Blood Cells

Bloods cells have multiple functions from transporting the oxygen to all parts of the body to keep the immune system strong. They are produced by bone marrow and are vital to keeping the body alive. Red blood cells, white blood cells, and platelets are the most important cells which run the body. Platelets prevent blood loss due to damaged vessels, white blood cells prevent infections, and red blood cells transfer oxygen to the organs in the body.

Muscle Cells

Muscle cells develop the muscle tissues, which enables all the bodily movement in the body.  There are three types of muscle cells, namely skeletal, cardiac, and smooth. Skeletal muscle tissue attaches bones to the muscles that help with voluntary movements. Cardiac muscle cells form the involuntary muscles which operate the circulatory system. The smooth muscle cells make the involuntary muscles that line body cavities and protection to organs.

Fat Cells

Also known as adipocytes are a major cell component of adipose tissue. It contains droplets of fat stored in the body to be used as energy when needed. The fat cells become round and swollen when the fat is stored inside them. When the fat gets used by the body, the cells shrink back to their initial stage. Adipose cells also produce hormones which can also influence sex hormone metabolism, insulin sensitivity, blood clotting, and more.

Nerve Cells

Nerve cells are also known as neurons which are the basic unit of the nervous system. The nerves connect the brain, spinal cord, and body organs via nerve impulses. The central cell body comprises of neuron’s nucleus associated cytoplasm, and organelles
